Introduction: M-Wire and rotating motion of ProTaper Gold (PG), G-wire and reciprocating motion of WaveOne Gold (WOG) are the recent innovations using thermal treatment. Therefore, a study was planned to evaluate the shaping ability of ProTaper Gold and WaveOne Gold using cone beam computed tomography (CBCT)
Methodology: Thirty freshly extracted mandibular teeth were selected and stored in saline until use. All teeth were scanned pre and post operatively using CBCT. All teeth were accessed and divided into two groups. (1) Group 1 (PG, n = 15): Instrumented with ProTaper gold (7%/#20). (2) Group 2 (WOG, n = 15): Instrumented with primary file (7%/#20) WaveOne Gold. Sections at 3, 5, and 7 mm were obtained from the pre and post-operative scans. Volume of removed dentin, apical transportation and centering ratio were measured and statistically analyzed.
Results: WaveOne Gold showed lesser apical transportation and volume of removed dentin when compared to ProTaper Gold groups at 3, 5 and 7 mm. WaveOne Gold showed lesser degree of straightening when compared to ProTaper Gold.
Conclusion: This study concluded that WaveOne Gold maintained the original canal anatomy better and did not remove excess dentin while chemomechanical preparation as compared to ProTaper Gold.
